FireFly Version 3

The FireFly 3 is an ATmega128rfa1 powered wireless sensor device with the following specifications:

  • 16MHz with 32KHz low-power clock
  • Integrated 802.15.4 compatible 2.4GHz radio
  • 16KB RAM, 128KB FLASH, and 4KB EEPROM
  • 2 UARTS, I2C, SPI, GPIO, ADC

There are two primary versions of the FireFly platform. One is a development board that has USB connectivity for built-in programming and an easy connection to a PC. We also have a miniature low-cost version without the USB connectivity and user IO that can be used for deployments.
